1. Quiche in a mug

2. Jacket sweet potatoes with tuna

Substitute normal potatoes with a sweet potato for a lighter bite. This dish is also super easy, efficient and cheap. Top with a drizzle of sweet chilli sauce and you've got restaurant style goodness, without the price tag.

3. Microwave fried rice

4. Microwave ratatouille

The prep work for this involves ten minutes of cutting up veg and seasoning. And a lunch time of happiness. It also uses a lot less oil than you'd usually use in the more conventional way of cooking ratatouille.
